What a coincidence. I caught a Pompano at the mouth of the Suwannee this weekend. No pics but yours is much larger. Mine was 12" to the fork. My first. We caught sandtrout and whiting out the wazoo but were mostly small. (ended up with a mess to eat) Mom hooked and fought a 5' long salt-water gar all the way to the boat then we had a huge school of black drum move in on us. Must have been spawning because I emptied my box in attempt to hook one to no avail. They hung around for 2 hours. I posted here to "catfish" off your picture, hope you don't mind.
Nice catch.
